P._agg Change Description /Brief Justification of Change l 12-l & 3 Remove defmition 12.1.1. " ACTION" and include in new definition 12.1.22.
" SURVEILLANCE" The definition for surveillance more accurately describes the three activities performed in section 12 with frequencies guided by Table 12.1-1. The three activities are; remedial measures for inoperable components, activities to verify component operability, and activities to ensure offsite dose limits verified. This definition more clearly establishes activities performed in this section.
12-1 A statement was added to the definition for " DOSE EQUIVALENT I-131" stating that the definition is not used in the defueled condition. Radioactive I iodine is no longer a concern due to decay since permanent cessation of operation.
12-2 A statement was added to the definition for " OPERATIONAL MODE" stating j n that the definition is not applicable in the defueled condition. The station is !
U defueled and will never enter an " operational mode" 12-3 The definition for " Ventilation Exhaust" was changed to " Gaseous EfIluent" and discussion of iodines was removed. Gaseous efiluent more accurately describes the whole system and iodine is no longer present due to decay and permanent cessation of operation. A statement was added to the definition for
" WASTE GAS HOLDUP SYSTEM" stating that the system is no longer used and useful in the defueled condition. This is consistent with the DSAR and the current plant configuration. Venting of plant systems and decay has eliminated all measurable noble gas from the waste gas system and its feeder systems. In the defueled configuration there is no means for future introduction into the waste gas system.
12-4 In Table 12.1-1 delineating frequency definitions removed (Refueling Cycle) from the frequency notation for "R" Maintaining the 18 month frequency but no longer tied to refueling as refueling is an obsolete activity.

12-10 Eliminated the gas decay tank and its associated flow rate monitor. There is no activity present in the gas decay tanks or associated system requiring specific monitoring and automatic isolation. There is no functional need for a waste gas holdup system in the plant defueled condition. Eliminated the Air Ejector Off-gas Monitors. These monitors were only required in operational modes 1
& 2. The function of these monitors are not applicable in a permanently defaeled plant. The containment purge and vent section was clarified with the addition of Efiluent in the title. The paniculate containment purge monitors 1(2)RT-PR09C are eliminated. The current requirement is to have the containment SPING or the purge monitor available to purge. In the rare event that a purge is needed, the containment SPING is still required with its auto actuation function. Venting of containment should not be required in the defueled condition as integrity should never be set. However, in the event a vent is needed the monitoring provided by the containment SPING remains unchanged The applicable mode was changed to the condition " venting or purging" The title of section 2 was changed to "EfIluent Ventilation" to more {
accurately describe the monitors' function. The applicability was changed for j p)
("
ORE 0014 to " supply or exhaust fans operating" to reflect the condition the monitor is designed to monitor. The applicability for 1(2)RIA-PR49 channels
)
l & 5 was changed to "All Times" as this monitor should be available at all times to monitor any activity passing through the vent stack to the public. All iodine monitoring was eliminated as radioactive iodine is no longer a concern due to decay and permanent cessation of operation. The miscellaneous cubicle monitor ORT-PR12A was eliminated. This monitor as well as the iodine monitors were only required in operational modes 1,2,3,4 and as such have no applicability in the defueled condition. The applicability for the flow rate monitors for the vent stack was changed to " supply or exhaust fans operating" to reflect the condition the monitor is designed to monitor. The fuel building ,
area monitors were added to facilitate the ODCM as the guiding document as the monitors are removed from the Tech Specs. However, the changes do not i conflict / relax requirements in the current Tech Specs. This change adds an additional requirement above Tech Specs for ORE 0005 and ORT-AR03. The new requirement changes to whenever fuel is present to satisfy a new criticality monitoring requirernent as well as the Tech Spec fuel handling accident applicability.

12-5 Changed the general requirements to Plant monitoring instead of emuent monitoring and delineated the specific emuent requirements as for emuent monitors. This facilitated use of the ODCM as the guiding document for the component cooling monitors as they are ITDC but no longer applicable in current Tech Specs.
12-6 Added "Emuent" into the titles for the emuent monitors. Added a " plant System Monitors" for the component cooling monitors. Consistent with the definition " SURVEILLANCE" definition change changed Action to Surveillance. Changed Applicable Modes to Applicable Condition and changed applicability for the effluent monitors except the fire sump compositer to " liquid release through that pathway" The fire sump compositer was changed to "All Times" for clarification. The component cooling monitors were changed to " monitoring an active CC loop" More accurately describes the activity for which the monitor is required to perform its intended function.
12-7 Changed the word " ACTION" to " SURVEILLANCE" Added a statement to {
Surveillance 2 requiring development of a plan to return the monitor to service I ifit is inoperable for 30 days. Ensures the monitor does not remain inoperable indefinitely. Added Surveillance 4 for the component cooling monitors.
Maintains the current surveillance with the additional requirement to develop a plan to return the monitor to service ifit is inoperable for 30 days.
I 12-8 Changed the titles on sections 1-3 to more accurately describe the monitors as i emuent . monitors. Added a section for the component cooling monitors with the standard operability surveillances.
12-9 Changed the general monitoring requirements from " Gaseous Emuent" to
" Plant" and delineated the specific emuent requirements as for the emuent monitors only. This facilitates inclusion of Emergency and Fuel Building monitors into the ODCM as the guiding document instead of Tech Specs.
O
, , ATTACIIMENT A m
Description of ODCM Changes for OSR/001/99 12-12 This is different than the current remedial surveillance. These monitors were moved to the ODCM from Tech Specs where they had an applicability of operational modes 1,2,3,4,7. Zion will never enter an operational mode again.
These monitors are not credited in the mitigation of any accident described in the DSAR. In the absence of radioactive iodine their charcoal beds no longer have a function. This surveillance is appropriate to ensure the monitors are available to perform monitoring functions described in the current GSEP.
Surveillance 15 was added for the new Control Room and TSC area monitors moved from Tech Specs to the ODCM. The surveillance was changed to include the ability to initiate an alternate means of monitoring with alarm capabilities. These monitors are for area habitability. Local alarming monitors would indicate the need to assess the area for habitability.
12-13 Operability surveillances were removed for those monitors deleted from the ODCM. Operability surveillances were included for the newly added fuel building area monitors. These new surveillances are consistent with those listed in current Tech Specs.
g 12-14 Arranged the emergency monitors into one group and delineated operability I 4 surveillances for the newly added Control Room and TSC monitors. The required surveillances did not change from current practice 12-15 Added a footnote for the fuel handling area monitors (consistent with current requirements) to source check daily during fuel handling activities.
12-16 In section 12.3.1.A.2. the requirement to have at least 200,000 gpm of dilution flow for release of radioactive liquid wastes was removed. This was too restrictive and conservative. The release requirements do not change. The station must meet release concentration limits. This change allows the freedom to adjust dilution and discharge rates to meet the limits. Again, section 12.3.1.B.3. was changed removing the requirement to have a circulation water pump operating on the discharge path during release. This was changed to require appropriate dilution and discharge flows are used to meet release concentration limits.
12-19 Requirements for analyzing for radioactive iodine were eliminated. Due to decay and permanent cessation of operation iodine is no longer present in the waste / effluent streams at Zion.

Description of ODCM Changes for OSR/001/99 12-11 The steam line monitors and containment accident monitors were eliminated.
They were only applicable in operational modes. They are not required or applicable in the defueled condition. The vent stack accident monitors were '
relocated to the Emergency Monitoring section. An Emergency Monitoring section was created to facilitate the ODCM as the guidance document instead of Tech Specs. The monitors are no longer applicable in Tech Specs but must be controlled until the GSEP plan changes are approved by the NRC.
Monitoring for iodine has been eliminated as it is not a concern in the defueled condition. This section includes the Tech Support Center (TSC) SPING, the Control Room SPING and Area monitoring for these areas. This section also includes the high range vent stack noble gas channels.
12-12 This page lists the remedial activities required for each monitor if it is unavailable to perform its function when required by its associated applicable condition. The gas decay tank surveillance has been eliminated because the monitor has been eliminated. Current " action 8" was deleted as there was no associated monitor for this remedial activity. The surveillance for the vent stack flow panel was changed from a frequency of once per shift to once per day. This is consistent with the frequency for the vent stack monitor itself. i Also, the vent stack flow can be determined at any time from the number of exhaust fans operating per unit. The vent stack SPING mid and high range noble gas channel surveillance number changed from 10 to 9, but the actual remedial surveillance did not change. Current " Action 11" was deleted as the associated Fuel handling accident in containment monitors (AR04) were deleted. Current " Action 12" was deleted as there was no associated monitor for this remedial activity. The statement " collected with auxiliary sampling equipment" was deleted from the surveillance activity for the vent stack SPING particulate channel. The surveillance remains unchanged, this change allows freedom in determining how to meet the surveillance activity. A new Surveillance 12 was added for ORT-AR03. The surveillance is consistent with current practice with the additional requirement to perform daily area surveys.
The survey requirement was added to meet the added function of the monitor as a criticality monitor. Surveillance 13 and 14 were added for the other two fuel building area monitors. These remedial activities are consistent with current practice. For the Control Room and TSC SPING assigned Surveillance requirement 9.

A sample will be collected once per day instead of once per shift. This is appropriate with no active secondary side available as a release path.
12-25 Thyroid dose was changed to organ dose to more accurately reflect the dose limit. Organ dose is the general dose requirement, the limitation on the thyroid would be included as an organ.
12-26 Eliminated gu decay tanks as a mode of release. This is consistent with the DSAR. The gas decay tanks have been vented and there is no process by which noble gas can be added to the waste gas system. Deleted footnote (a) from containment releases. The station can never " start-up, shutdown, or have power changes" For continuous vent stack release path, removed the requirement to collect and analyze for radioactive iodine. Due to decay and permanent cessation of operation iodine is no longer present in the waste /emuent streams at Zion.

[ practicable, the test shallinclude the operation of the ACTUATED EQUIPMENT V] as well (i.e. pumps will be started, valves operated, etc.).
12.1.5 A COMPOSITE SAMPLE is one in which the quantity of liquid sample is proportional to the quantity of hquid waste discharged and in which the method of sampling employed results in a specimen which is representative of the liquids released.
12.1.6 A CONTINUOUS RELEASE is the discharge of liquid or gaseous wastes of a nondiscrete volume (e.g. from a volume or system that has an input flow during the release).
12.1.7 A CONTINUOUS SAMPLING FREQUENCY is uninterrupted sampling with the exception of sampling interruptions of short duration for routine activities (e.g. filter replacements).
12.1 e DOSE EQUIVALENT l-131 shall be that concentration of I-131 (microcurie / gram) which alone would produce the same thyroid dose as the quantity and isotopic mixture of I-131,1-132, 1-133,1-134, and 1-135 actually present. The Thyroid Dose Conversion f actors used for this calculation shall be those listed in Table 111 of TID-14844, " Calculation of Distance Factors for Power and Test Reactor Sites" or Table E-7 of NRC Regulatory Guide 1.109 Rev.1, dated October,1977.

TABLE NOTATIONS For certain mixtures of gamma emitters, it may not be possible to measure radionuclides in concentrations near their sensitivity limits when other nuclides are present in the sample in much grcater concentrations. Under these circumstances, it wik be more appropriate to calculate the concentrations of such radionuclides using observed ratios with those radionuclides which are measurable.
- b. A COMPOSITE SAMPLE is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged and in which the m1thod of sampling employed results in a specimen which is representative of the liquids releas ad.
- 1) To be representative of the quantities and concentrations of radioactive materials in liquid effluents, all samples taken for the ctmposite shall be thoroughly mixed in order for the composite sample to be representative of the effluent release.
- 2) The weekly and monthly Proportional Composite samples are not required provided that (1) the analysis required for each of these composite samples has been run on each batch discharged, and (2) a monthly record of radionuclides discharged (isotope and quantity) is maintained.
- c. A BATCH RELEASE is the discharge of Iquid wastes of a discrete volume. Prior to sampling for O analyses, each batch shall be isolated, and then thoroughly mixed to assure representative V sampling.
- d. A CONTINUOUS RELEASE is the discharge of liquid wastes of a nondiscrete volume; e.g., from a volume of system that has an input flow during the continuous release.
- e. The principal gamma emitters for which the LLD specification applies exclusively are the l following radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cv 137. Ce-141, !
and Ce-144. This list does not mean that only these nuclides are to be detected ard reported.
Other peaks which are measurable and identifiable, together with the above nuchce shall also !
be identified and reported. Nuclides which are below the LLD for the analyses shall be reported j as "less than" the nuclide's LLD, and shall not be reported as being present at the LLD level for ~
that nuclide. The "less than" values shall not be used in the required dose calculations.
- f. If the fire sump composite sampler is inoperable, grab samples shall be taken from the turbine building fire sump once per day.

- a. The LLD is the smallest concentration of radioactive material in a sample that will be detected with 95% probability with 5% probability of falsely concluding that a blank observation represents a "real" signal.
For a particular measurement system (which may include radiochemical separation):
LLD = 4.66 s p A E
- V 2.22 Y
- exp (-AAt)
Where:
LLD is the lower limit of detection as defined above in picocuries (pCi) per unit mass or volume, sois the square root of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute),
A is the number of gamma rays emitted per disintegration for gamma ray radionuclide analysis (A = 1.0) for gross alpha, strontium, and tritium measurement.
E is the counting efficiency (as counts per gamma),
V is the sample size (in units of mass or volume),
2.22 is the number of disintegrations per minute per picocurie, Y is the fractional radiochemical yield when applicable (otherwise Y = 1.0)
A is the radioactive decay constant for the particular radionuclide, and At is the elapsed time between midpoint of sample collection and time of counting (for plant effluents, not environmental sample).
The value of soused in the calculation of the LLD for a detection system shall be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma ray spectrometry, the background shall include the typical contributions of other radionuclides normally present in the samples l Typical values of E, V, Y, and at shall be used in the calculation. The background count rate is calculated from the background counts that are determined to be within i one FWHM (Full Width at Half Maximum) energy band about the energy of the gamma ray peak used for tne !
quantitative analysis for that radionuclide.

ZION Revision 4 June 1999 S_ases 12.3.2.C This Section is provided to implement the requirements of Sections ll.A Ill.A and IV.A of Appendix 1,10CFR Part 50. The limiting Condition of Operation implements the guides set forth in Section ll.A of Appendix 1. The ACTION statements provide the required OPERATING flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept "as low as is reasonably achievable." Also, for fresh water sites with drinking water supplies, which can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are excess of the requirements of 40CFR 141. The dose calculations in the ODCM implement the requirements in Section Ill.A of Appendix ! that confomlance with the guides of Appendix l be shown by calculational procedures based on models and data, such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the dose due to the actual release rate of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109; Calculation of Annual Doses to Man from Routine Releases of Radioactive Effluents for the Purpose of Evaluating Compliance with 10CFR Part 50, Appendix 1. Revision 1 October 1977 and Regulatory Guides 1.113 " Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of implementing Appendix 1," April 1977.
This Section applies to the release of liquid effluents from each unit at the site. For shared radwaste treatment systems, the liquid effluents from the shared systems are proportioned among the units sharing the system.

- 3. If the sample type or sampling location (s) required by Table 12.5-1 become(s) permanently unavailable, identify suitable altemative sampling media for the pathway of interest and/or specific locations for obtaining replacement samples and add them to the Radiological Environmental Monitoring Program as soon as practicable. The specific locations from which samples were unavailable may then be deleted from the program.
Prepare and submit a controlled version of the ODCM within 180 days including l a revised figure (s) and table reflecting the new location (s) with supporting information identifying the cause of the unavailability of samples and justifying the selection of new location (s) for obtaining samples.
Surveillance Reauirements 12.5.1.B.1 The Radiological Environmental Monitoring samples shall be collected from the locations specified in the ODCM and analyzed pursuant to Table 12.5-1 and the detection capabilities required by Table 12.5-3.
Bases 12.5.1.C The Radiological Environmental Monitoring Program required by this section provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implement: Section IV.B.2 of Appendix l to 10CFR50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring.
The initially specified monitoring program will be effective for at least 3 years of commercial operation. Following this period, program changes may be initiated based on operational experience.
The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLD). The LLDs required by Table 12.5-3 are considered optimum for routine environmental measurements in industrial laboratories.
It should be recognized that the LLD is defined as a before the fact limit representing the capability of a measurement system and not as an after the fact limit for a particular measurement.
Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, LA., " Limits for Qualitative Detection and Quantitative Determination-Application to Radiochemistry," Anal Chem.
40, 586-93 (1968), and Gartwell, J.K., " Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSIS
^
TABLE NOTATIONS (1) This table contains lower limits of detection for analyses beyond the requirements of Table 12.5-1. This table does not imply that only these nuclides are to be detected and reported; other peaks which are measurable and identifiable in the analyses required by Table 12.5-1 shall be reported in the Annual Radiological Environmental Operating Report, (2) Required 'Jetection capabilities for thermoluminescent dosimeters used for environntental measurements shall be in accordance with the recommendations of Regulatory Guide 4.13.
(3) The Lower Limit of Detection (LLD) is defined, for purposes of these specifications, as the smallest concentration of radioactive materialin a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5%
probability of falsely concluding that a blank observation represents a "real" signal.
For a particular measurement system, which may include radiochemical separation, the LLD is defined as follows:
4.66 So + 3/to LLD = ----------------------
(E) (V) (2.22) (Y) (exp (-).at))
4.66 So LLD ~ ----------------------
q (E) (V) (2.22) (Y) (exp (-).At))
]
Where: 4.66 So >> 3/to LLD = the "a priori" Lower Limit of Detecthn (picocuries per unit mass or volume),
so = the standard deviation of the background counting rate or of the counting rate of a blank sample, as appropriate (counts per minute),
41'otal Counts Ib E = the counting efficiency (counts per disintegration),
V = the sample size (units of mass or volume),
2.22 = the number of disintegrations per minute per picocurie, Y = the fractional radiochemical yield, when applicable,
). = the radioactive decay constant for the particular radionuclide (sec"),
to = counting time of the background or blank (minutes), and O

For dose calculation, a garden will be assumed at the nearest residence.
Acolicability: At all times.
' Action:
With a Land Use Census identifying location (s) that yields a calculated dose or dose commitment, via the same exposure pathway 20% greater than at a location from which samples are currently being obtained in accordance with Section 12.5.1, add the new location (s) within 30 days to the Radiological Environmental Monitoring Program given in Chapter 11 of the ODCM Station Annexes. The sampling location (s), excluding the control location, having the lowest calculated dose or dose commitment (s), via the same exposure pathway, may be deleted from this monitoring program after October 31 of the year in which this Land Use Census was conducted. Submit in the next Annual Radiological Environmental Operating Report documentation for a change in the ODCM including revised figure (s) and table (s) for the ODCM reflecting the new location (s) with information supporting the change in sampling locations.
The nearest industrial facility shall also be documented if closer than the nearest residence.
O h Surveillance Reauirements 12.5.2.B The Land Use Census shall be conducted during the growing season, between June 1 and October 1, at least once per calendar year using that information that will provide the best results, such as by a door-to-door survey, aerial survey, or by consulting local agriculture authorities. The results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report.
Bases 12.5.2.C This specification is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the Radiological l Environmental Monitoring Program given in the ODCM are made if required by the results of this census.
This census satisfies the requirements of Section IV.B.3 of Appendix i to 10 CFR Part
- 50. An annual garden census will not be required since the licensee will assume that there is a garden at the nearest residence in each sector for dose calculations.

DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSIS TABLE NOTATi'ONS At = the elapsed time between sample collection, or end of the sample collection period, and the time of counting (sec).
Typical values of E, V, Y, and 41 should be used in the calculation.
It should be recognized that the LLD is defined as a before the fact limit representing the capability of a measurement system and not as an after the fact limit for a particular measurement.
Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally, background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report.
(4) If no drinking water pathway exists, the value of 15 pCill may be used.
(5) A value of 0.5 pCill shall be used when the animals are on pasture (May through October) and a value of 5 pCi/l shall be used at all other times (November through Aprit).
(6) This LLD applies only when the analytical separation and counting procedure are specific for this radionuclide.
(7) This is the minimum required LLD, however, environmental samples analyzed off-site will be required to use 200 pCi/l.

This annual summary may be either in the form o, an hour-by-hour listing on magnetic tape of wind speed, wind direction, atmospheric stability, and precipitation (if measured), or in the form of joint frequency distributions of wind speed, wind direction, and atmospheric stability. In lieu of submission with the Annual Radiological Environmental Operating Report, the licensee has the option of retaining this summary of required meteorological data on site in a file that shall be provided to the NRC upon request.
A single submittal may be made for a multiple unit station.
